AbstractHigh speed digital systems laboratoryהמעבדה למערכות ספרתיות מהירות

2

the project goal is to Create a controller for two bio-simulator boards with 128 analog output channels at each board .Bio potential detector measures the electric potentials on the surface of living tissue . Bio potential detection is useful in many medical application such as ECG, EMG, AND EEG MONITORS. Therefore is also useful to have the ability to test the Bio potential detector by a bio potential simulator.

System descriptionHigh speed digital systems laboratoryהמעבדה למערכות ספרתיות מהירות

On each boards there are 4 DACs with 32 analog outputs, and there is also an ADC for calibration of the board.Each board comes with a FPGA that controls directely all the components on the board. The FPGA sends the data to the analog at rate of 40k cycels per second.The host)standart PC( responsible on the calibration, and on sending data to the FPGA.
